Final answer:
On MDCT, the final reconstructed slice thickness is determined by the detector configuration and acquisition parameters, which include the number of detectors, beam collimation, and pitch.
Step-by-step explanation:
On MDCT (Multidetector Computed Tomography), the final reconstructed slice thickness is determined by the detector configuration and acquisition parameters chosen by the radiologic technologist or radiologist. These parameters include the number of detectors, the beam collimation, and the pitch. The ability to reconstruct images at various slice thicknesses after the scan has been performed provides great flexibility in diagnosis, allowing for better localization and characterization of abnormalities within the body.
The reconstruction algorithm is a mathematical process that uses the acquired CT data to generate the final image. Different algorithms can be used to reconstruct the image with different slice thicknesses.
